The branched conjugated copolymer based on triphenylamine and 3-hexylthiophene has been synthesized via Suzuki polycondensation reaction in the presence of Pd(PPh₃)₄ and K₂CO₃ as catalytic system. This conjugated polymer named poly(triphenylamine-branched-3-hexylthiophene) (P(TP-b-3HT)). The reaction was carried out at 100°C in 24 hours in the toluene media. The average molecular weight of obtained conjugated polymers was 24000 g/mol by gel permeation chromatography (GPC) with polydispersity index of 1.8 The structure of P(TP-b-3HT) was determined by ¹H NMR and FTIR spectrum, and optical properties of obtained conjugated polymer was characterized via UV-Vis.
